Hi John,
Since you see the GUI, the input drivers (both USB HID and PS/2) have come up, which is promising.
That's interesting - could the USB driver be initialized, but crash on an interrupt (or something like that)?
indeed. It looks very much like that.
To take the USB driver off the critical path for using Sculpt, you may give the attached patch a try. It prevents the input filter from obtaining an input session from the USB driver. If our assumption is correct, you should be able to interact with Sculpt using the laptop's keyboard and track point (driven by the PS/2 driver).
This just goes to show how dependent we are on USB - I can't think of a way to get data on or off this machine without it. (No optical drive, and I didn't buy the dongle for the "mini-ethernet" port.)
It's a little strange that it boots off the USB stick all the way through displaying the component graph. I'm assuming it uses the BIOS up to a certain point, then hands control over to the Genode drivers.
The boot image is loaded into memory by the boot loader, which uses BIOS calls. Genode's USB driver is not used at this stage.
If we can pinpoint the problem to the USB driver, there is still the open question of how to investigate it. I hope that the ability to interact with Sculpt will give us some clues, in particular by looking at /report/log in the inspect window.
Cheers Norman
